Epson WF-5620 "les données de chiffrement ont expiré"

i had the same problem and tried so many troubleshoots but finally found a solution.

I was to able to scan but could not print using wifi

go to settings and go to add printer session

click on the globe icon

type the IP address (to find the IP address, go to your printer and print the etat wifi/reseau )

select protocol LPD

hope it helps
